Graduate Advisees

Jerome BarnerJerome Barner

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Natural Resources Mgt

Brannon BarrBrannon Barr

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Previous Graduate Study: University of North Texas (Environmental Science)

Personal Statement
I am interested in determinants of species distributions and abundances at the community and landscape scale, related species interactions such as colonization, competition, predation, and symbiosis, the evolution of life history characteristics, and how these phenomena are related to resource supply rates and nutrient fluxes.

Franklin DiggsFranklin Diggs

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: FRM Forest Ecosystem Science & Appl

Personal Statement
I am broadly interested in the evolution of symbiosis and in particular mutualisms and the way that these interactions shape the ecosystems that contain them. My specific work is work concerns mycorrhizal systems.

Graduate Research Topic
My work involves investigating root colonization by mycorrhizal fungi across depth and stand age and the use of molecular techniques in monitoring mycorrhizal systems. I work out of the White Mountains in New Hampshire as part of the Multiple Element Limitation in Northern Hardwood Ecosystems.

Yang YangYang Yang

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Minzu University of China

Personal Statement
I'm interested in forest-based environmental issues that raised currently. I'm more focused on nutrient cycling in forests and the way to assess the forest health.

Graduate Research Topic
My project is detecting the change in tree tissue chemistry over time in Northern Hardwoods. Research,conducted in Huntington Wildlife Forest,will show a change in concentrations of tree nutrients in different tree components over time and detail the uncertainties of processing long-time detecting studies in tree nutrients..
